Western blot analysis for Bax, Bcl-2, and AMPK was done as the same method of Park et al. (2020) (link). After homogenizing liver tissues on ice, the tissues were lysed using lysis buffer. Protein content was calculated using Bio-Rad colorimetric protein assay kit (Bio-Rad, Hercules, CA, USA). After separation of 40-μg protein on sodium dodecyl sulfate-poly-acrylamide gels, it was transferred to the nitrocellulose membrane. Then, the reaction mixture was treated with primary antibodies such as mouse β-actin antibody (1:3,000; Santa Cruz Biotechnology), mouse Bcl-2 antibody (1: 1,000; Santa Cruz Biotechnology), rabbit Bax antibody (1:1,000; Santa Cruz Biotechnology), and rabbit AMPK antibody (1:1,000; Santa Cruz Biotechnology). Horseradish peroxidase-conjugated anti-mouse antibodies for β-actin and Bcl-2 and horseradish peroxidase-conjugated anti-rabbit antibodies for Bax and AMPK were used as the secondary antibodies. The expression for bands was analyzed using enhanced chemiluminescence detection system (Santa Cruz Biotechnology).
